Harry Deane played for and managed the Fort Wayne Kekiongas for part of the 1871 season, and later played for the Baltimore Canaries in 1874. He had previously been a backup player in the outfield for the 1870 Cincinnati Red Stockings, before the creation of the National Association, and since that was a famous team, he had likely played amateur ball before that.
Deane was one of the oldest players on the Kekiongas at age 25, and became the manager after dissatisfaction grew with the first manager Bill Lennon. Although the Canaries were an older team, he was also one of the oldest players on that team, but nevertheless had a batting average slightly higher than the team average.
